This model is based on the classic arcade game, Frogger. The object of the game is to get the frog, found at the bottom of the view, across the traffic and river to a safe lily pad on the other side.
There are two main obstacles to overcome, the road and the river. The road has cars and trucks moving at various speeds that are liable to run over the frog. Once you have crossed the road safely, you must overcome the danger lurking in the river. Unfortunately, you will die if you jump in the river, so you must keep moving towards the lily pads by jumping on the logs or sets of turtles moving back and forth in the river's current.
You must also avoid getting pushed off the edge by a log or turtle. In addition, in the later levels, some of the turtles will dive under water -- if you happen to be standing on them you will drown! Finally, you must also get across the board before the allotted amount of time runs out.
Cast of characters:
Gray squares: This is the road. You can jump on this, but watch out for vehicles.
Green Patches: This is grass. You are pretty safe here.
See if you can get through all of the levels.
Try to beat your previous time.
Try to make as few jumps as possible in the time allotted.
Try to use as few lives as possible.
Determine how many jumps it would take to get across the board without obstacles.
Determine how many jumps it would take to get across the board with obstacles.
How does each of the two questions above relate to the time it takes you to complete a level?
If you take just as many jumps with obstacles as without, why does it take different durations of time to get across?
Write your own levels by altering the code in the Code tab.
Add some bonuses or additional hazards.
Implement a scoring system.
Write a robot script that will move your frog automatically.
This model uses breeds to implement the different moving game pieces.
every command is used to control the speed of the game.
user-message command presents messages to the user.
mouse-ycor are used to detect and handle mouse clicks.
